Will he know it when he sees it?

LONDON — Elton John said Wednesday that he owns a photo of two naked girls taken by award-winning photographer Nan Goldin that was seized by police at a British gallery over concerns it amounted to child pornography

John confirmed ownership of “Klara and Edda Belly-Dancing” in a statement on his Web site. He said that it is among 149 images comprising Goldin’s “Thanksgiving” installation.

If nothing else, we know the photos hold no prurient interest for the owner.
